Here ya go buddy... my last tanks:
Both Accords share the same commute - 20 miles 70 MPH interstate, 15 miles urban driving in Birmingham, AL (downtown driving, stop and go, red lights). I'm a pretty easy driver, but have no problem gunning it to merge in a hole or get the lead on someone whose lane I need to be in. Throw in a trip around the beltway (I-459) at 50 miles or so interstate extra too in a typical tank. In that commute, I see:
2006 Honda Accord EX. 2.4L 5-speed Automatic. 26,600 miles - 30 MPG on my last tank (no A/C), typically closer to 28.5-29. I get service as the maintenance minder tells me to.
1996 Honda Accord LX. 2.2L 4-speed Automatic. 176,900 miles - 27 MPG on last tank, this is typical. Higher speeds on the interstate really hurt mileage in this car because of shorter gear ratios. I get the oil changed every 3,000 miles, and recently replaced the air filter (spark plugs about 25k miles ago).
This what you are looking for?

First 2 tanks in my new 08 LX, 177hp 4cyl, 5 spd manual. So far a stead7 25.5 MPG.
Commute is about half and half, 50%relaxed rural surface streets, 50% rural 2-lane highway 70mph.
First tank was on stock Dunlops, second tank is on chunky Cooper snow tires. I did do a nice relaxed highway and 55mph back roads trip to Keene and back the other day, filed up before I left then whyen I returned and got a bit over 27MPG.
I'm hoping by spring, once winter-blend gas is done, once the engine has a few thousand miles on it, and once I get the lower rolling resistance tires back on, I'll be getting a good 28-30 in my regular commute.

08 Accord EX-L Nav Automatic. 700 miles driven thus far
City driving only, long stop lights, many of them and within a few blocks of each other, normal driving, not hard accelerations nor stops, no air on, florida fall season. I drive maybe 3 miles one way which hurts the mpg
18.3 miles per gallon twice now
Highway 90% 10% city and I got 33 miles per gallon.

I have posted regularly my mpg. But, I've quit since the numbers were getting monotonous I have about 3500 miles on the vehicle now. I use 85 octane because of my high altitude (average driving at 6200-6500 feet). I am very conservative with braking and letting the engine race. I rarely let the engine race above 4000 rpm and I try to not let the engine shift up hills. I, however, drive fast . . average80-85 on the interstate and 70-75 on two-lane. Also, my driving is almost never over flat terrain. No matter where I go, there are usually elevation changes of 1500 to 3000 feet.
I have little experience on commuting --my mpg numbers generally involve 350 to 450 miles of mixed interstate and two-lane roads per calculation.
I am averaging right around 27 mpg. It has been as bad as 24 (with Denver interstate traffic) and up to 31 with a hefty tail wind for 200+ miles.
As stated , I use 85 octane gas that does contain 10% ethanol.
Hope that info is useful!

I got over 32 mpg on my weekly trip to the eastern part of WA state. Lots of rain and huge puddles of standing water on the mountain pass, which also made speeding up and slowing down a part of the trip. Pretty windy on some portions and there was some city driving as well.
This is pretty good for the colder weather and all that rain. I've been over 40 mpg with slower speeds and much better weather. The trip computer showed over 37 mpg on the return trip but that will change by the time I fill up.

My 2004 V6 A/T Accord EX Coupe averages 20 to 22 mpg on a day-to-day basis with local commuting and some highway. On long flat highway trips with not much interfering traffic I can get 30 to 31 mpg keeping it under 75 mph.
My wife's 2008 I4 A/T Accord EX-L Sedan hasn't had a complete fillup yet, so no statistics. I'll know in a few days.

My 2003 Accord LX I4 is averaging about 27 mpg with about half city/half highway and a very short commute, 6 miles each way all highway(save the mile it takes me to get to the highway). On a long trip 300 miles I got around 35. I had a 95 EX I4 and that averaged about 23 under the same conditions.

I have to say, thegraduate and blane are correct on this issue, are you are just plain wrong.
"When you fill up, how do you know the tank has just the amount of fuel it needed? Did the nozzle stop too early? Or, too late?"
This initial statement is correct. The particular fuel pump could shut off earlier or later than your last fillup, which could effect your MPG calculation. But this only applies when you are FILLING UP your tank, when the nozzle senses the tank is filled.
When you are only getting small increments of fuel (partial fillups), there is no possibility of the pump shutting off too early or too late. It shuts off when you want it to. So if you pump 2 gallons of gas, you get 2 gallons of gas.
"So, after x miles, you might calculate from 13.1 gallon (one fillup), or from 14.3 gallons (multiple fillups)."
This doesn't make sense. You wouldn't be making "multiple fillups", you would be making multiple partial fillups, which would not be effected by the pump shutting off too early or too late.
"Almost always you will find that computation based on multiple small fill ups will result in poorer fuel economy than would on a full tank fill up. Try it. I have."
I think understand...you are confused as to what is being discussed. They are not computing MPG based on topping off the tank with "multiple small fillups". They are only completely filling the tank one time.

What you said mattgg1 is what I wanted to say, you just beat me to it.
Something else to mention is that if a pump reads wrong, say, it shows an extra .1 gallon pumped for every 10, that difference will be smaller if you only pump one gallon (meaning it would be off by .01). It's not a difference of .1 with every addition of fuel, the amount that the pump is "off" will correlate to the amount of gas pumped. The "click" issue isn't an issue at all until you FILL the tank.

MPG = 22.06
60% city (stop n go)
Initially I was disappointed, but when I considered the following I guess it wasn't too bad.
1. 1st tank
2. I'm constantly changing speeds for engine break-in reasons ie. no cruise.
3. winter gas
4. Temp. has been in the 20's
5. I swapped the oem Michelin's for the Bridgestone Turanza Serenity's. Softer
rubber - I think. Of course I don't know how much softer any rubber is at 20F.
Also, the "trip computer" on the Navi said 22.1mph when I filled up. I was pretty impressed with it's accuracy.
